The Forest Sector is a sector of Lyoko. It is mostly a complex series of paths intertwining between thousands of trees. Large open areas does not occur like those in the Desert Sector and Ice Sector. It also has a lot of hollow tree trunks which connects areas of the Forest Sector and has often saved the lives of our Heroes.
Despite the fact that paths are narrow in this sector, X.A.N.A. often sends his largest monsters, such as Megatanks and krabs, to attack our heroes when they are trying to deactivate a Tower there.
